The Best Advice on Planting Tomato from 19+ Gardening Experts

Tomatoes are one of the easiest fruits to grow indoors or outdoors. In fact, it is best recommended for first-time gardeners. However, your tomato garden will not yield a good harvest if you fail to apply the necessary growing conditions. Such conditions include the right temperature and proper lighting.

​To aid you on your tomato gardening journey, we reached out to some of the best tomato gardening experts to give you the proven and tested tips to grow tomatoes successfully, as well as some techniques to revive your dying tomato plants. This article is divided into three main questions, namely:

  • What should you do when your tomato plant is dying?
  • What should the ground temperature be to plant tomatoes?
  • How much light does a tomato plant need to grow?

Without further ado, let’s get started!

  • What should you do when your tomato plant is dying?​

There could be a number of reasons why tomato plants have problems with growth. Check if your tomato plant's leaves are curling up or get darker and dried up, especially the bottom ones. These can be signs for a more serious plant disease. In order to be sure, cut off one of the stems. If you see a brown ring on the cut, grub up the plant, as it probably has been infected by a bacteria. If the ring is not present, look for the problem elsewhere.

Aphids could be another reason. You can strike them down with a chemical, but I'd advise you to go for an organic version. Get a few packs of lacewing eggs, or attract those beneficial insects naturally by planting fragrant plants, such as garlic, catnip or oregano. The little flies will munch on the aphids, and all you have to do after is just get rid of the dried leaves - the new ones will grow untouched.

External conditions also influences tomatoes to a good extent. They don't like too cold a night or too hot a day. If the soil is too dry, the situation worsens. Then you have to mulch the dirt with sawdust or straw. Composting will also work in this case.

  • How much light does a tomato plant need to grow?

​Tomatoes are light-loving plants. Growing the sprouts, you'd need them facing towards southeast or south, but, quite often, natural light is not sufficient. When mixing it up with artificial light, you have to bear in mind a few factors.

- Combined lighting must lead to a stronger light stream in general, rather than to increase in the light day, i.e., it's best for you to turn on the artificial lamp during the day, as a way to help the natural light, rather than during mornings and evenings.

- Count in the COP (coefficient of performance) of the lamp, when you choose it. The COP of the regular electrical lamp is 8-9%, the luminescent one is around 11-13%, whereas the halogen lamp has a COP of 25-28%. As you can see, the regular one has a very low COP and it also radiates too strong short-wave infrared beams, that lead to plant stalks being too elongated. The luminescent lamps emit quite a beneficial lighting, but do not provide normal sprout growth, because of the low power of the light stream. The most effective ones are halogen lamps - with the highest COP and the least amount of short-wave beams of light. Place the source of light around 25 to 30 cm away from the plants, which will increase the thermal energy as well and it will be quite useful for the climate.

Unfortunately, the light feeding is the hardest to regulate at a home environment. It's much easier to provide a complex and full mineral feeding of your seedlings, which will, to a certain extent, compensate any shortage of light

  • What should you do when your tomato plant is dying?​

Unless it’s a simple issue of too much or too little watering, your dying tomato plant may be beyond recovery. Best thing might be to pull it and follow the sanitation protocol below. It also depends on the growth stage. If it’s early on, look for signs of root damage or disease. There’s an early tomato blight that can be devastating. Treating the plant with organic or non-organic methods might salvage it through the season. Note also, that as the season progresses and the plants grow taller, certain wilts and/or fungi naturally begin to take hold. We’ve not had a tomato of any variety, make it into fall without serious die back and loss of vitality. It’s just the nature of the end-of-life cycle for tomato plants. They’ve worked hard all summer and now it’s time to let them go.

Here are strategies that will reduce the impact and spread of disease.

Rotation: Keep track of where you’ve planted tomatoes (and related nightshade crops like potatoes, eggplant, and peppers) so that you can plant in a different part of the garden– a part that has had no nightshade plantings for at least 3 years. Planting in fresh straw bales.

Sanitation: Many diseases are born by the overwintering and spread of spores. When pruning or collecting fallen plant materials never put them into your general use compost pile. We burn ours in a burn pile or burn barrel. They can also be buried or bagged and discarded. Anything you use that contacts the ailing plant must be sanitized by spraying or dipping in alcohol (our preference). This also goes for your hands with sanitizing hand cleaner (our preference) or soap and water. Do this before touching other plants. All of these measures are important toward preventing the spread of disease in your garden.

Mulching: - A good mulch of clean straw (our preference) keeps water from splashing from the ground up onto the plant and leaves. Wet leaves without proper aeration can contribute to blight.

Pruning: – You may also slow the spread of disease by carefully pruning dead, diseased, and dying leaves off the plant stem. Be sure to follow the sanitation protocol (above).

Resistant Varieties: If at all possible, plant tomato varieties that are resistant to Verticillium wilt, Fusarium wilt, Nematodes, and Tobacco mosaic virus (look for "VFNT" on the tag or package info). Later stage diseases are quite common even with the VFNT label as the plants mature and produce fruit. Note that the VFNT indicates “resistant” not disease proof

  • What should the ground temperature be to plant tomatoes?

The key to when you plant tomatoes has more to do with your last frost date than the actual ground temperature. Look up your USDA Plant Hardiness Zone and also check in with your local Agricultural Extension folks to identify any micro climates that might affect your last frost date. You can then plant seed or set out transplants accordingly. Just be ready to apply a protective cover in case there’s a cold snap. After all, the Zones are based on averages.

  • How much light does a tomato plant need to grow?

The standard minimum is six hours per day. We have two gardens. One gets about six and the other about eight. The eight hour garden produces far more than the six hour garden.

  • What should you do when your tomato plant is dying?

That question is a tough one. There are so many factors. It could be a virus, bacteria, soil issues, culture. You MUST find out the issue to treat it properly.

Spend some time and do the research to gain the knowledge of WHAT the issues is, what causes it and what steps need to be take to remedy the problem.

  • What should the ground temperature be to plant tomatoes?

I like to see the soil temperature above 50 degrees before transplanting tomatoes.The top soil can feel warm, but 6 inches from the surface may still feel cold. You can plant the tomatoes when the overnight lows are reliably above 50F.It will still work, but it’s best to wait when the soil temperature is above 50F.

  • How much light does a tomato plant need to grow?

Light is important but so are some other "factors." Be sure to select an area with a well-drained soil and ample sun (at least 10 hours a day). Also, try to select an area sheltered from strong winds.

  • What should the ground temperature be to plant tomatoes?

Tomato seeds germinate best in warm conditions, preferably around 80°F (27°C). Once germinated, seedlings that have hardened off can be transplanted into garden soil with ground temperatures at least ~70°F (21°C). Night air temps should not fall below 45°F(7°C).

  • How much light does a tomato plant need to grow?

Tomato plants like lots of light. Plant them in garden spaces that receive a minimum of 6-8 hours of direct (full) sunlight. If you’re not sure of the best location, follow the pattern of sunlight in your garden for a full day and make note of the area and duration of full light and partial sunlight, as well as, the spaces that experience full and partial shade.Then choose the right spot to grow your tomatoes.

  • What should you do when your tomato plant is dying?​

The two most important responses are:

1. Be familiar with what problems other gardeners in your area have. For example, at my present location everyone has problems with nematodes, and whenever a tomato starts dying, that's the best bet. Someplace else, it might be a nutrient deficiency typical of the soil of that area, or any other of a long list of possibilities. Local successful gardeners are the best source for help.

2. Unless you have a local Extension agent able and willing to look at your plants, probably the next best thing to do is to go to the Internet and search images of sick tomato plants matching your plant's symptoms. Google has an image-search feature. Go into that section and search for images based on key words. For example "tomato diseases leaves yellow" or "tomato diseases stem black." A variety of thumbnail pictures will appear and you browse for plants looking like yours.

These are first-aid approaches. When confronted by a sick plant, the best of all worlds is to have developed a general basic knowledge about soil, the different kinds of diseases, nutrient deficiencies, etc. This is information that can be acquired over time, from different sources, especially local gardeners.​

  • What should you do when your tomato plant is dying?​

Depends on what is happening, does the plant have blight? if so take all fruit off that are not effected and put in the garbage (not compost) need to remove from the property.If the plant has disease, would be best to destroy and plant cover crops.

If the plant is in your greenhouse, in order to keep the plant producing, keep trimming the bottom leaves, and ensure that you are continuing to water, feed the plant if it is still producing flowers and fruit. Depending on your area.

  • What should the ground temperature be to plant tomatoes?

We generally suggest waiting until the soil is at least 68F and the nightly temperatures are not going below 10 degrees celsius or 50 F.

  • How much light does a tomato plant need to grow?

Full sun, at min. 8 hours of sunlight.

  • What should the ground temperature be to plant tomatoes?

We know how nature is amazing. If it keep you away from your garden because too cold or too hot, it is definitively not time to plant tomatoes. If you can stay there confortably, you may be closed to the right temperature to plant. But is that wright for all plants? Almost if you consider planting between 75°F and 90°F

For Tomatoes, we recommend to seed at 80°F (26°C) but transplants can be operate from 55°F (13°C) in Urban and Sub-Urban Areas.

Don't forget to water your transplants with a large quantity of water the first time and place them on a trellis

  • How much light does a tomato plant need to grow?

That point will be a key of success for Urban Gardeners. Your tomatoes will need a minimum of 6 hours in continuous sun or 8 hours in discontinuous. Yes, consider trees, buildings, garden fences that can occur your garden place. For balcony garden, make sure you containers are high enough to receive sun. Don't forget that your plants could be to small at the beginning and be hide from sun by the balcony itself.

For indoor gardeners, when your plants are placed right on your windows hedge, provide its enough water from the bottom. It will boost them!

If you think your garden is not sunlit enough, plant cheery or small size tomatoes instead of big one. They ripen faster.

  • What should you do when your tomato plant is dying?

There are three common reasons for your tomato plants to start dying:

- The first is over or under watering. Dig into the soil around the base of your tomato plant about an inch and assess whether it is too wet or too dry. Water accordingly, and see if your plant perks up.

- The second reason your plant might look like it is dying is that is over or under fertilized. Over fertilization occurs when too much nitrogen is applied to your plants. You'll notice burned tips of the leaves. Undernourished plants that are craving fertilizer will appear stunted and pale. They also stop blooming and producing fruit. A good practice is to apply an organic fertilizer for tomatoes at least every 4 weeks.

- The third common reason that tomato plants die is from infection. If you see an overwhelming pest problem, then address it accordingly. However, if there are no pests and your plant is turning yellow or brown, it may be infected with a bacterial, viral, or fungal disease. There is no treatment for many tomato diseases, and there very well may be nothing you can do to help. If your plant looks very sickly and is not producing any more fruit, it might be best to pull it up so the disease can't spread

  • What should you do when your tomato plant is dying?​

I've never personally experienced a dying tomato plant, all of mine have grown successfully year after year - I use a lot of rock dust (minerals) and sea soil, and only water every couple days - they grow to be quite enormous!

  • What should the ground temperature be to plant tomatoes?

I always wait until after the last frost to plant tomatoes. They do not like cold temperatures.

  • How much light does a tomato plant need to grow?

Tomato plants require full sunlight to grow. Always pick a spot that gets at least 8 hours of direct sunlight a day.

  • What should the ground temperature be to plant tomatoes?

Tomato seeds need at least a 50 degree Fahrenheit (10 degree celsius) ground temperature to germinate when sown indoors or under cover. If sown directly into the ground outside, temperatures need to be more than 60 degrees Fahrenheit (15 degree celsius) - a good indicator is to wait until night air temperatures are a minimum of 55 degrees Fahrenheit (12.5 degree celsius), by then, the daytime temperatures are much warmer.


I’m Oz Gardener. I’m an avid gardener and this site allows me to communicate with and help other gardeners.

I’ve spent a lot of time over the past twenty years learing about gardening and I figure that it would be wasteful to keep all of this information just to myself. I’ve had a garden ever since I can remember. I’m currently gardening on a significant portion of a six acre plot of land that I bought in southern New Jersey (or, as the locals say, “South Jersey”). Most of the gardeners that I know really like to share ideas and help other gardeners. And I enjoy reading and writing about gardening when I can’t actually be in the garden.

  • When should I plant my tomatoes?

It never fails that as soon as Spring is in the air garden and department stores start selling tomato plants far too early in the season to be planted in the open soil. Tomatoes are tropical plants and they need soil temperatures of 60 Degree or more to grow. One can easily be fooled into thinking the soil is warm if the air is warm, however testing the soil with a thermometer is the only way to know for sure. If you don’t have a soil thermometer, wait until the nighttime temperature in your area is constantly 55-60 Degrees before you plant tomatoes. If patience is not in your vocabulary, raised beds and containers warm up faster than open soil and can allow you to plant a few weeks sooner. Spend the early days of Spring getting your garden soil ready by breaking up the surface and adding generous amounts of compost. Not only will this help the sun’s warm rays penetrate the soil, but also the soil will be in perfect shape when the time to plant arrives.

  • What should you do when your tomato plant is dying?​

What should you do when your tomato plant is dying? in early season, try and figure out WHY...is it yellowing? not enough potassium. Add dried crushed banana peel. Is it needing water? Remember to water at least 1 inch deep at a time. Is it laying on the ground? Stake it up.

  • What should the ground temperature be to plant tomatoes?

What should the ground temperature be to plant tomatoes? I find that the plants do better when the ground temp is at least 75-80 degrees, with air temps 80 during the day.

  • How much light does a tomato plant need to grow?

How much light does a tomato plant need to grow? it's better to have at least 12-14 hours to get the best fruit.

  • What should you do when your tomato plant is dying?​

Depends why its dying, I have found that LOTS of water goes a long way for struggling tomato plants. If its under attack from bugs, you have to kill the bugs and then tend to the plant with water and nutrients. If the plant is damaged in a storm and some of the vines have broken or are badly bent, you can plant the broken pieces by putting 6 inches to a foot under soil and providing lots of water - it will root and start a second plant!

  • What should the ground temperature be to plant tomatoes?

I am in Texas and I must admit it is much warmer here when we plant - it needs to be past the point of freezing of course. Here is an article about when to plant seeds. https://thehomestead.guru/seed-starting-calendar-2/

  • How much light does a tomato plant need to grow?

I have found that tomatoes in direct sunlight grow the biggest and reddest, those that are in the shade may grow vines and leaves, but the fruit will not be as significant.

  • What should you do when your tomato plant is dying?

Cutting off the dead leaves helps to keep disease from progressing. Tomato plants need at least 8 hours of sunlight to grow well. A ground temperature of at least 55 degrees F is best but warmer is even better. If tomato plants are dying it is usually either too little, or too much water. Adjust accordingly.

  • What should the ground temperature be to plant tomatoes?

Tomatoes are pretty forgiving when it comes to soil temperature, unlike other warm season vegetables like cucumbers, peppers and eggplant, to name a few. Tomato transplants can be planted when the soil temperature is around 55º F, but growth will be slow. If you’re wanting to direct seed tomatoes, however, you’ll need to wait until the soil is above about 72º F.

  • How much light does a tomato plant need to grow?

Tomatoes like full sun in most areas of the country, as do most vegetable plants. Full sun means at least 6 hours of full sun. In very hot areas, like the Gulf Coast regions, most of Texas and southern Florida, tomatoes do well with morning sun and some afternoon shade or even dappled light most of the day.

  • What to evaluate if your tomato plant is dying

There are 5 basic things to check when your tomato plant is dying:

1. Is it a determinate or indeterminate plant?

2. How wet is the soil?

3. Are there any insects on it or signs of insect destruction?

4. Does the foliage look deformed, suggesting microorganisms?

5. What has the recent weather been like?

  • Is it determinate or indeterminate?

Not all tomato plants have the same kind of life cycle. Some are particularly bred to set fruit nearly all at once and then be done. These are called determinate tomato plants. In my experience, not all tomato plants designated as determinate have an obvious end of life cycle, but some do and there is nothing to be done about it other than plant a new plant or wait for the next season.

Indeterminate tomato plants have the advantage of living and setting fruit as long as the plant lives. The problem is that many indeterminate plants take a long time to grow large enough to set fruit, so can be unreliable for harvest in shorter season regions. Also,indeterminate plants often don’t set a lot of fruit at once, so if you are hoping to preserve tomatoes in bulk, this can be inconvenient.

  • Are you watering it correctly?

Don’t assume that a dying plant that looks dry needs water. It can look that way because its roots are rotting from too much water. At best, you can try to let it dry out significantly more between watering and see if it recuperates, but if the roots are toofar gone it will not recover.

  • Are insects eating it?

Most insects that damage tomato plants can be observed, which helps a lot with identification of the particular insect. The main thing with insect pests is to notice the infestation in time. This is a good reason to wander around your garden regularly even if you are caught up with weeding, watering, and harvesting. Sometimes it only takes a couple of days for insects to devastate a plant.

The two main insect predators that I have had to deal with are tomato horn worms and little black beetles called flea beetles. Fortunately, tomato plants don’t taste very good to many insects, but the ones that like them can devour them quickly. I also have the advantage of living in a high desert climate, which tomatoes thrive in during the summer. A thriving plant is much less susceptible to insect damage.

For tomato horn worms, I have hand picked or dusted the plants with diatomaceous earth. However, I have never had a serious infestation of them. For the flea beetles, I sprayed the plants with Bonide Eight just once or twice and didn’t have any more trouble.

  • Are your tomato plants infected by microorganisms?

Dealing with pathogenic (disease causing) microorganisms is three-fold. First, try to choose varieties of tomatoes that are resistant to diseases prevalent in your region.Second, don’t plant your tomato plants next to plants that are known to share diseases with them. Thirdly, remove infected plants promptly.

Curling yellow leaves is one symptom that may be caused by a virus, but is also idiopathic (of unknown cause). Either way, the best thing is to remove it. Such a plant will rarely produce anything worth eating and may put other plants at risk. Unfortunately,this is the best action for any plant that is infected, so even it if is clinging to life, it is best to get rid of it.

  • Understand how the weather affects your tomato plants

Tomato plants are the epitome of a warm weather crop. They cannot handle frosts or freezing temperatures. While all of your broccoli and lettuce may look just fine after alight frost, your tomatoes will suffer a death blow.

If a frost happens in the spring, it will likely severely damage the young plant. There may be time to plant a replacement. If it happens in the fall, there is a possibility that some fruit and leaves have survived on the inside of the plant. The plant will probably not make a come back, especially if the colder days of fall are imminent.

Sometimes covering plants can protect them, if it is just a light frost. If the temperatures plunge too deep or are cold for too long, there is not much to do other than wait for warm weather again.

  • How to decide when a tomato plant is actually dying

As you can see from the above discussion, the crux of the matter is how stressed the plant is. If a lot of the plant has died, it is frequently not worth trying to save it. On the other hand, I have saved a tomato plant in my greenhouse that died all the way back tothe roots from a frost, but then came back to life in the warmth of indoors. It all dependson what you want to experiment with and how much work you want to put into it. Eitherway, in the right conditions, you should be able to grow magnificent tomato plantssooner or later!

  • What should you do when your tomato plant is dying?​

A dying tomato plant. If it is yellowing/browning or just any color other than green- pull itout and compost it. It will not recover. If a dull green or going a pale green - water a lot early and then aerate.

  • What should the ground temperature be to plant tomatoes?

Temperature for tomato planting ideally 12-16 degrees. In a cold greenhouse, the ideal time is early to mid April as soil temperatures should be a little higher. Propagation temperatures- the same but, ideally a little higher.

  • How much light does a tomato plant need to grow?

Light. As much as it can get. No upper limit. Lower limit hinders pollination and therefore yield. Directly. The connection between light and yield is huge. So- put down white pads, use white strings and generally do all you can to lighten up in the variable days of April and May.

  • How should we water tomato plants?

Properly watering your tomato plants is without question one of the most crucial steps in growing healthy and tasty tomatoes in your garden.

The best way to water your tomatoes is deep watering at the root level of the plant. Watering with this technique will help your plants develop strong roots and have less stress. I like to use a handheld watering wand to direct the water. You can also use a soaker hose. A soaker hose is an excellent way to ensure the water is going to the soil directly around the roots of the plants.

Try to avoid getting water on the foliage of your plants. Wet leaves can be a recipe for blights and other diseases to spread.

You should also take into account the soil type, outside temperatures and the size of the plant to make watering decisions. Follow the general guideline of about “2 inches (5 cm.) of water per week” for tomato plants. Rain counts! Check the soil regularly and make adjustments to your watering if temperatures rise or soil is dry or wet.

Good watering techniques done regularly will reward you with healthy plants and a tasty crop of tomatoes!

  • What Should You Do If Your Tomato Plant is Dying?

The most important step to redeeming your tomato plant is identifying the problem. There are 3 main issues that cause tomato crop failure- infestation, under watering/overwatering, and disease.

Infestation is the easiest to diagnose as damage will be visible on the leaves or fruit. A quick, non- toxic fix for infestation is to spray the leaves with a solution of water and dishwashing liquid. For more stubborn pests, a mild pesticide may be required.

Under watering and overwatering are the most common cause of wilting yellowed leaves. This can be diagnosed with a simple check of the soil for dryness or swampiness.

There are a wide variety of diseases that affect tomato plants, each with their own set of symptoms. Once you have detected a disease, treating with fungicide and bactericide will help.

  • What Should the Ground Temperature Be for Planting Tomatoes?

The ideal temperature will ensure a bountiful harvest! Seedlings and young plants should be kept at around 18 degrees. For outdoor planting, daytime temperatures of 15 degrees or over is best. Night time temperatures shouldn’t fall below 10 degrees. 21 degrees is the perfect temperature for optimal germination.

  • How Much Light Does a Tomato Plant Need to Grow?

8-12 hours of decent, natural light will give the best yields. However, in British climes, this isn’talways possible. The minimum amount of light needed for a tomato plant to thrive is 6 hours.

  • What Should You Do If Your Tomato Plant is Dying?

What you should do depends on why your tomato plant is dying. It could be the usual: too much or too little water, and that’s easy to fix. If you grow your tomatoes in containers, definitely watch the eater: it’s really easy to miscalculate the water needs of a container. On hot days, make sure to water twice a day.

If you made sure too much or too little water is not the problem, it could be any number of garden pests attacking it. If your tomato is not completely destroyed by pests, take care of removing the attackers and give it a bit of organic fertilizer to give it a boost.

And sometimes it’s just better to remove the infested tomato to save the rest of your garden

  • What Should the Ground Temperature Be for Planting Tomatoes?

Tomatoes LOVE warmth, and should not be planted until any danger of frost has passed. It’s best to wait until day temperatures are a above 70 degrees, and night temperatures don’t dip below 55 degrees. Tomatoes might survive in lower temperatures, but they won’t thrive.

  • How Much Light Does a Tomato Plant Need to Grow?

Tomato plants need at least 6 to 8 hours daily to thrive. And while they love to be in the sun, they hate too much heat. So, the hot afternoon sun with scorching heat isn’t good for them. Plant tomatoes in a spot that gets morning sun, and you’ll have happy tomato plants.

Hi there! I’m Lucy, and I’m a self-confessed garden fanatic. Gardening has always been a passion of mine and will always be my favorite pastime. Now that I am married and have one adorable son, I have the time to write and share my personal experiences with other garden enthusiasts like me.
